MACHINE FOR CUTTING BARREL-HEADS.

Specification of Letters Patent N o. 20,864, dated July 13, 18581.

T o all whom it may concern:

Be it known that I, A. H. CROZIER, of Oswego, in the county of Oswegoand State of New York, have invented an Improved Machine for Turning theHeads of Barrels, Oasks, &c.; and I do hereby declare the following tobe a correct description of the same, reference being had to theaccompanying drawings, in which- Figure l is a perspective view of themachine complete; Fig. 2, a side elevation of the same showing thecutting tool in position to bevel the edge of the head; Fig. 3, asimilar elevation showing the saw in posi ton for cutting the head intothe circular form, and the cutting tool removed from the work; Fig. 4,an enlarged view of the beveling tool; and Fig. 5, a vertical sectionthrough the disks showing the mode in which they are driven.

The same part is marked in all the figures by the same letter ofreference.

The nature of my invention consists in an improved arrangement ofmachinery for cutting and beveling the heads of barrels, casks &c., inwhich .both the cutting and beveling tools are controlled by a singlewinch or lever worked by the operator, and in which it is not necessaryto stop the motion in order to put in the material or take out thefinished work-all as hereinafter more particularly described.

To enable others to make and use my improved head turner, I will proceedto describe its construction and operation.

I place the machine in a strong frame of iron A; the driving power isapplied, from any suit-able prime mover, to pulleys B and C on the endof the main shaft D. This shaft D carries pulleys E and N, and worm H.Pulley E by a cord or band drives spool F on the saw shaft. Pulley N, byband O, drives roller P on the cutter shaft. Worm H drives pinion I onend of cross shaft J. On the other end of said shaft is a pinion Kgearing into cogs L on the lower face of disk M. The lower end of theshaft f of disk M works in a socket g attached to the frame of themachine. On this shaft is a collar between which and socket g is placeda spiral spring e through the center of which shaft f plays. The upperpart of sha-ft f passes through an upright journal box 71,. The spring etends to force the collar z' up against the journal box la raising theshaft f' up so that cogs L will be out of gear with pinion K. Above diskM, and

detached from it is disk R attached to shaft S which has a screw threadon its upper portion, as shown, controlled by wheel or head T. Byturning wheel T disk R is raised or lowered as desired. Disk R isloosely pivoted to the lower end of shaft S, so as to be capable ofindependent revolution upon it. When the disk R is brought into contactdisk M by screwing down shaft S, the two disks will be capable ofrevolving together. The disk M, when not pressed down by the disk R isheld up by the act-ion of spring e so that the cogs L are out of gearwith pinion K, as seen in Fig. 3, and disk M will not be kept in motionby the revolution of said pinion. When, however, the disk R is forceddown upon disk M, the spring e, is compressed, and the disk M is lowereddown so that cogs L will fall into gear with pinion K and the two disksbe revolved by the revolution of that pinion.

The shaft of the dished saw G revolves in journal boxes that form partof the sliding arc U which works in guide V. This guide is connected byrod WV with rock lever X. The rod IV has two stops, a and b, upon it,the end of lever X moving freely between them. The rock lever X ispivoted at its center to the frame of the machine as shown. It movesbetween guides (see Fig. l) the outer one of which Z has a rack upon itsupper surface. Into this rack plays pinion Y which is pivoted to lever Xand turned by winch a. Attached to lever X are the journal boxes X X, ofthe cutter shaft CZ. Fixed to this shaft is roller P which is driven bya band from pulley Y. On the top of shaft Z is the beveling tool orcutter Q. The back and forth movement of winch a will cause lever X tovibrate on its center and bring tool Q up toward, or away from disk M.'Ihis winch is controlled by the operator.

The operation of the machine is as follows: Power being applied topulley C, the saw G and cutting tool Q are respectively set in motion byreason of their connection with pulleys E and N. The disk R being drawnup out of contact with M, the cogs L are not in gear with pinion K, andboth disks are therefore at rest. The stuff to be turned and beveled isplaced on disk M; disk R is screwed down upon it untilv disk M issufficiently depressed to throw cogs L into gear with pinion K, whenrevolution will be imparted to both disks and to the material clampedbetween them. The operator then turns the winch a to the right whichbrings the saw Gr up to its work of giving the circular form to thehead. Vhen that is accomplished, the winch a is turned to the left whichwithdraws the saw Gr and brings the tool Q up to cut the bevel on theedges of the head. The stops Z) and c on rod W enable the operator tocommence bringing up the cutter before withdrawing the saw, and viceversa, thus saving time. When the beveling is accomplished, the disk R,is retracted by means of wheel T; the spring e throws disk M up out ofgear with pinion K; its motion is easily arrested; the finished headremoved, and a fresh blank inserted for a repetition of the operation.
